You are really very welcome. Speaking for myself, I've received so much help, in various ways, from TP that if I can give even a little bit back, I'm happy to do so.
All I can do is roll my eyes at your description of the hospital staff. You do wonder if they get any training at all, sometimes. Unfortunately, there is no class for common sense.
Given your description of your mum and her pre-hospital activity levels, I'd say you should definitely go for day care/the day centre/lunch club/singing for the brain/anything you can find. A day program will not only keep her occupied and socializing, but also might be able to provide her with "jobs" that allow her to feel useful and helpful. I know, I know, something else for your to-do list.
It sounds like you're doing an amazing job and we certainly wish you all the best.
